Pregnant with Wolff Parkinson White... Is natural childbirth ok?

I was diagnosed with Wolff Parkinson White as a teenager and was labeled high risk for my first daughter. Nothing happend to me during that pregnancy or the other two. I was heavily druged for all of them and felt no pain during that actually delivery. However I want to have a natural childbirth this time around with no IV no epidural or pitocin. I am concerned if I tell my doctor I want natural she'll say no. I have had no symptoms since I was around 16 and have not had to be on medication since I was 18. Is there any need to be worried with a natural birth?
